 Flagger implements several deployment strategies (Canary releases, A/B testing, Blue/Green mirroring)
-using a service mesh (App Mesh, Istio, Linkerd, Open Service Mesh, Kuma)
-or an ingress controller (Contour, Gloo, NGINX, Skipper, Traefik) for traffic routing.
-For release analysis, Flagger can query Prometheus, Datadog, New Relic, CloudWatch, Dynatrace,
-InfluxDB and Stackdriver and for alerting it uses Slack, MS Teams, Discord, Rocket and Google Chat.
+and integrates with various Kubernetes ingress controllers, service mesh and monitoring solutions.
 
 Flagger is a [Cloud Native Computing Foundation](https://cncf.io/) project
 and part of [Flux](https://fluxcd.io) family of GitOps tools.
